Acuity Scheduling trigger

Overview

Receives webhook events from Acuity Scheduling when appointments are scheduled, changed, rescheduled, canceled, or when orders are completed. The incoming webhook payload contains the object ID and action; optionally resolves the full object details via the Acuity API. Use this trigger to automate workflows based on scheduling activity in Acuity Scheduling.

Node Type

Trigger — webhook (receives incoming HTTP callbacks)

Credentials

This tool requires Acuity Scheduling credentials. See the Credentials Guide for setup instructions.

Parameters

Parameter	Type	Required	Default	Description
Event	options	Yes	—	The Acuity Scheduling event to listen for.
				Options: appointment.canceled (fires whenever an appointment is canceled), appointment.changed (fires when the appointment is changed in any way), appointment.rescheduled (fires when the appointment is rescheduled to a new time), appointment.scheduled (fires once when an appointment is initially booked), order.completed (fires when an order is completed)
Resolve Data	boolean	No	true	Whether to resolve the full object data from the Acuity API. When disabled, only the webhook payload with the object ID is returned.

Output Data

Each delivered event produces one output item carrying the Acuity Scheduling webhook payload — id (the appointment or order ID), action, calendarID, and appointmentTypeID — plus three added fields:

• _trigger — always acuityscheduling_webhook
• _timestamp — ISO 8601 timestamp of when the request arrived
• _webhookEvent — the action Acuity reported

Reference the payload downstream by expression, e.g. {{ $json.id }} or {{ $json.action }}.

Example Configuration

Start a workflow whenever an appointment is booked:

{
  "type": "acuityscheduling_trigger",
  "parameters": {
    "event": "appointment.scheduled",
    "resolveData": true
  }
}

React to cancellations without resolving extra data:

{
  "type": "acuityscheduling_trigger",
  "parameters": {
    "event": "appointment.canceled",
    "resolveData": false
  }
}

Process completed orders:

{
  "type": "acuityscheduling_trigger",
  "parameters": {
    "event": "order.completed",
    "resolveData": true
  }
}

Trigger Behavior

• Activation: When the workflow is activated, a webhook endpoint is registered with the service.
• Deactivation: The webhook is automatically unregistered when the workflow is deactivated.
• Payload: The incoming webhook payload is parsed and output as workflow items.
• Verification: Supports signature verification where applicable.

Tips

This tool triggers workflows when Acuity Scheduling fires appointment or order webhook events. It is ideal for automating tasks that need to react immediately to scheduling changes or completed orders within Acuity. It produces a webhook payload, optionally with full object details, for further workflow processing.

• One node listens for one event. To react to several events, add one Acuity Scheduling Trigger per event, or use appointment.changed, which fires for any change to an appointment.
• The delivered payload identifies the appointment or order by ID. When a workflow needs the full record — attendee details, forms, pricing — follow the trigger with an HTTP Request node that fetches it from the Acuity API using {{ $json.id }}.
• Incoming requests are signature-checked against your Acuity API key, so a stale or third-party caller cannot start the workflow.
